rpcbind.socket failed to listen on sockets: Address family not supported by protocol

Failed to listen on RPCbind Server Activation Socket.

I stumbled upon this error on a CentOS 7.7 freshly installed server today. Funny thing is that i set up 2 servers via ansible and this issue happened only on 1 of them when i was trying to set up the NFS mounts.

Fixing is fairly easy:

sudo systemctl enable rpcbind.socket

sudo systemctl restart rpcbind.socket

sudo systemctl start rpcbind.service

sudo systemctl start rpc-statd.service

After this, mount your NFS share away. Should work just fine
